There have been several good suggestions, which have all been ignored because they were not what you wanted to hear, I guess.

Set your whole idle table to X degrees and your main table to Y degrees. Then log and see what you?re running at cruise.

.1 second is 100 milliseconds.

10 milliseconds is **.01** seconds

Thanks very much for this and the harness diagram!

I had a he** of a time getting my Miata with cammed LS3 to drive smooth in those conditions. I finally have it running very smooth. Look for my thread in this subforum titled "Driveability Tune...

Updated the tune as of 1/31/23 ... the car is driving smoother than ever. I put a lot of this down to the recent changes to the Throttle Follower Torque step up/down values in the Idle/Airflow tab. ...

Changed that, and it had no effect. I left it changed anyway because what I had was obviously wrong.

Back to working on DFCO, the car is running really well driveability-wise other than that. ...

A search on "ETC Scaler 5636" led me to a thread that says the '09 (and later?) 92mm throttle bodies open a bit more than the previous ones. GM adjusted the scaler value appropriately. Mine is...

I use that scalar value because it's what was in the GMPP tune that came with my controller for this (originally LS376/480) crate engine. It's a 92mm throttle body.

I had quite a bit of "fun" getting the LS3 in my Miata to drive smoothly at low load and low rpm (which describes 99% of street driving in a car like this). Even the stock tune that came in the GMPP...

I appreciate your willingness to speculate. With my old eyes, I read that as 126,xxx something. I'm doing some wiring on the car right now, so can't drive it for a few days. I'll look into this...

I had posted in another thread and got some feedback that looked interesting. https://forum.hptuners.com/showthread.php?55216-VSS-DFCO-on-GMPP-LS7-with-E67-VCM&p=636430&viewfull=1#post636430

That seems like a good guess ... but what controller/engine is this on? I have none of that in my circa '09 E67 tune.

I don't find a wire for CFCO in the ECM pinout that I have as part of the controller docs. Mine is a relatively early ECM, I bought the crate motor and controller in late '09.

Thanks very much for the explanation.

I **have** changed the VSS config. So I will scale it as suggested in that post, and see what happens. It's possible I'll be looking for a production ECU. ...

Thanks for the help.

My VCM scanner shows MPH all the time (no actual speedo in this car). So the ECU doesn't seem to lose mph as in the thread you referenced. Also, my tach works fine.

Ancient thread, but I don't see a resolution here. I'm trying to enable DFCO on *my* GMPP E67, and I'm starting to think that it's turned off in the GMPP controllers.

OP, if you're still here,...

So here you go. This is a capture of the log, and a screenshot of my DFCO set up.

I'm in 6th gear, 66 mph, so that should enable DFCO. I'm at .088 cyl air at 1833 rpm, so that should enable...

From looking at the log, it seems that everything is met except TPS. I knew that before I posted.

I was hoping somebody would be able to tell me what flavor of TPS is the one that's used in the...

Have you seen this thread? I found it very useful... https://forum.hptuners.com/showthread.php?86215-Quick-guide-to-simultaneous-VVE-MAF-calibration-for-gen4

The method discussed in that thread...

This is a GMPP LS376/480 controller (E67). The cam, heads, and intake have been upgraded since the the original LS376/480 went in the car (a Miata).

I'm trying to get the DFCO to work. This is...

I go on the ***assumption*** that the lowest (cyl_air * rpm) is better for economy.

So my car running in 6th might be .230 cyl air, 1600 rpm, and in 5th .200 cyl air, 2400 rpm. Since .230*1600...
